UNITED STATES PATENT OEEICE.

ARTHUR OBRIEN, OF HELENA, MONTANA.

SANITARY CLOSET.

SPECIFICATION forming' part of Letters Patent No. 456,678, dated July 28, 1891.

Application filed February 24, 1891. Serial No. 382,607. (No model.)

T 0 all whom t may con/cervi,.-

Be it known that I, ARTHUR OBRIEN, a citi- Zen of the United States, and a resident of Helena, in the county of Lewis and Clark and State of Montana, have invented certain new When the door of the closet is opened, communication between the bowl and soil-pipe is made and a supply of water for flushing the bowl turned on. The closet is automatically thrown into either position for use or non-use by the opening or closing of the door.

I will give a detailed description of my invention and its Inode of operation, referring to the drawings as occasion requires, and will then point out in the claims the features and combinations which I desire to cover by Letters Patent.

Referring to the drawings, in which like parts are indicated by similar reference-letters wherever they occur throughout the varions views, Figure l is a horizontal section through a closet-room with the door open, Fig. 2 is a similar view with the door closed and the bowl and seat folded back. Fig. 3 is a view in side elevation of the bowl and its attachments in the position shown in Fig. l. Fig. 4 is a detail View in rear elevation of the bowl, showing the position of the cut-off valve when thecloset is in the position shown in Fig. 2. Fig. 5 is a plan view of the device as shown in Fig. 3. Fig. (i is a plan viewof the pivoted valve member which supports the bowl.

The views shown in Figs. l and 2 are taken on the plane of line as, Fig.

Referring to the parts, A represents the walls of the closet-room, and A the door for the same.

C C is a soil and vent pipe, which is rig idly secured in place. A portion of this pipe is cut out, and the opposite ends are fitted with brass iianges c c. Between these iianges is fitted the brass bowl-supporting piece D, Fig. (i. The ends of this piece are dressed od true, as are also the adjacent faces of the iianges c c', to form valve-joints between the ends of the piece D and the iianges. The piece D is eccentrically pivoted between the iianges by the bolt d, which passes through the iianges and piece D. The upper flange is also perforated to receive the lower end of the vent-pipe E. The piece D is centrallyperforated at d2 and eccentrically perforated at d3. In the position shown in Figs. l, 3, and 5 the central perforation registers with the soil and vent pipe C C. The eccentric perforation d3 registers with the soil-pipe C and vent-pipe E when the part D is in the position shown in Figs. 2 and 4. The piece D is also provided with a branch or socket D', which communicates with its central perforation. The socket-opening is made Haring to receive the shank or discharge of the bowl F, which is rmly secured in it.

The body of the bowl, which may be of any approved form, is provided with an overflow which terminates in a pipe f. This extends into a dri p-pan G, secured around the soil-pipe C. The pan has a drain or waste pipe g, which may either connect to the soil-pipe or extend to the outside of the building. p

To the inside of the door is secured a bar or pipe II, which passes freely through a lug f, which projects from bowl F. The bar thus assists to support the bowl and also to turn it to the position shown in Fig. l as the door is opened, or to the position shown in Fig. 2 as the door is closed. The lug f is of course made to slide freely upon the bar or pipe I-I as the door is swung in either direction.

'lhe iiushing-tank I is a sheet-metal cylinder provided with a central tube or cylinder, which [its loosely over the Vent-pipe C. Its bottoni is firmly connected by a short pipe e' with the iiushing-rim of the bowl F. The top of the flushing-rin1 is concave and is perforated to receive water through pipe 7' through faucet J. The cock of the faucet is operated by a lever j', which depends downwardly in the path of two arms t" t2, which project horizontally from the tank. The supply of water is turned on and olf by means of these arms as the bowl is turned out for use or closed in, as shown in Fig. 2. In the position shown in Fig. 3 the arm fi has turned the faucet-lever j and opened the cock to turn a flow of water into the tank I. When the door is closed, as shown, Fig. 2, the arm 2 will turn the lever j of the cock in the opposite direction and close off the supply of water. It will thus be seen that the operation of my device is entirely automatic and actuated by the opening and closing of the door A.

To ventilate the closet-room when the doorV is closed, I provide a local vent-pipe K,whieh connects to the vent-pipe E above the valve D. This pipe is provided with a bell-mouth piece 7s; and to ventilate the bowl when the closet is in use the bar II may be made of tubing perforated upon one side near the hinge edge of the door to register with a chamber in the lug f, which communicates with the bowl F, as shown in broken section, Fig. l.

I wish it understood that I do not limit myself to the exact form and construction shown, as many mere mechanical 'changes may be made without departing; from the spirit or scope of my invention.

l. In a sanitary closet, the rigid pipe C C, having valve-ilanges c c', the bowl, and its supportD,pivoted to turnbetween the flanges, the part D being perforated to register with the soil-pipe when the bowl is turned for use and to close off the soil-pipe and register with the vent-pipe when the bowl is turned for non-use, combined and arranged substantially as shown and described.

2. The combination, as hereinbefore set forth, of the divided stand-pipe C C', having valve-anges cc ,the support D,eccentrically pivoted between said flanges, the vent-pipe secured eccentrically upon the flange c, the

port D, eccentrically pivoted between said flanges, the vent-pipe E, secured upon the upper flange, the bowl secured in support D, the flushing-tank I, fitted to turn around the pipe C, connected to the iushing-rim of the bowl and having arms t" i2, and the faucet J, having dependent leverj in the path of Vsaid arms z" 2, whereby a ilow of water is turned on when the bowl is turned ont for use and turned off when the bowl is closed against use, substantially as shown and described.

4. The combination of the closet A and door A', the bowl pivoted between the soil and vent pipes by valve connection and connected to the door, whereby connection is made to the soil-pipe when the dooris opened and cut off when the door is closed, the f1ushing-tank fitted to turn upon the vent-pipe and connected to the bowl, the arms c" i2, proj ecting from said tank, the faucet J, having dependent lever j in the path of said arms, the drip-pan G, secured around the soil-pipe, the pipe f', leading from the bowl to said pan, the vent-pipe E, arranged to register with the soil-pipe when the closet is ontof use, and the local vent-pipe K, connected to pipe E and having bell-mouth 7c, opening into the closet-room, substantially as shown and described.
